Highly efficient synthesis of extremely fine nano-SnO₂ photocatalytic materials by dealloying Cu₅₀Sn₅₀ alloy powders with mainly exposed {123} facts in η-Cu₆Sn₅

Abstract

Compared with Cu50Sn50 prepared by ball milling at 150 r min−1, Cu50Sn50 prepared at 300 r min−1 exposes more active facts in η-Cu6Sn5, thus leading to a shorter dealloying time, smaller particle sizes, and higher degradation activity of nano-SnO2.
